oh man.. i was just looking through pictures that i have.. and placing them into my I.D. folders.. and i discovered that im totally confused. i have 3 crabs that i have no idea who is who. the mix up is with charlotte,caligi, and brac. all threee are small dull colored PP's. and they are all in black and white turbo's usually i can tell them apart by shell coloring( which is how i know who casper is..becuase he has a huge white patch on his shell, otherwise i wouldnt be able to tell him apart either and there would be 4 in the mix up).. but right now only two of the three crabs are up.. so i cant compare all three to figure out who's who. its driving me nutso!! i guess im going to have to wait until the other look -aliek comes up so i can take them all out..identify them and take a TON of pictures to help me figure things out. is it possible to make small markings on the shells with something??( im thinking like dots or something) the only thing i can think of is permanent marker..and just do 1,2, and 3 dots on the shells so i can tell them apart. but would this be toxic to the crabs??? i figure that the dots would be small enoguh to not be harmful..but im not sure what to do.. any suggestions??? i dont think theres anyway i can live withmyself if i dont know what crab is what..i jusst GOTTA KNOW!!!!!!!!
